In heat transfer, the thermal conductivity of a substance, k, is an intensive property that indicates its ability to conduct heat. For most materials, the amount of heat conducted varies (usually non-linearly) with temperature. [1] Thermal conductivity is often measured with laser flash analysis. Alternative measurements are also established.

Thermal conductivity is a material property that describes ability to conduct heat. Thermal conductivity can be defined as "the quantity of heat transmitted through a unit thickness of a material - in a direction normal to a surface of unit area - due to a unit temperature gradient under steady state conditions"

The thermal conductivity of a material is measured in Watts per meter per degree Kelvin (W/m•K) following the S.I (International System) guidelines. The top 10 measured thermally conductive materials and their values are outlined below.

Thermal conductivity coefficients for insulation materials, aluminum, asphalt, brass, copper, steel, gases and more. Introduction to temperature - including Celsius, Fahrenheit, Kelvin and Rankine definitions - and an online temperature converter. Convert between thermal conductivity units.

Correspondingly, materials of high thermal conductivity are widely used in heat sink applications, and materials of low thermal conductivity are used as thermal insulation. The reciprocal of thermal conductivity is called thermal resistivity.
